STEP 6
- Mount 1pc Belimo actuator, LF24-SR (item 1) to the side panel with outdoor air damper (item 2). Align and insert
the hole of actuator to the shaft of the damper.
The default setting for outdoor air damper (item 2) shall be fully closed. Ensure this damper is in 'fully closed' position
before mount the actuator. Fail to do so will cause errors during the unit normal operation.
The surface of actuator which is facing upward/ outside shall be labelled with 'R' symbol to ensure the rotation of actuator
modulation in counter clockwise direction. Fail to do so will cause errors during the operation of unit with economizer
function.
There are 2pcs of Belimo actuator, LF24-SR (item 1) in economizer kit which come together with carton boxes.
Open the boxes and recognize the label on the wire. The actuator used in step 6 is the one with label 'OA' .

- Then, fastens 1pc screw M4x12 (item 14) on the support bracket of the damper. Do not fully insert the screw
thread, but only insert up to 2/3 of the screw thread. Mount the actuator to the support bracket by bringing the
support bracket closer to the shaft of damper. The function of screw M4x12 is to lock the actuator from slippery
during modulation.
- Next, put the clamp into the shaft and lock the actuator with circlip. Fasten the nuts of clamp tightly by using
adjustable spanner. Noted that clamp and circlip come together with actuator as the standard parts, you may
fi nd these parts inside the actuator box.
